If there was any joint pain or other reason for the visit, code that first. Otherwise, I would just use V43.65 for knee joint replacement status. If there is any instablility or other complication with the joint implant itself, use a Complication code.Pt was seen back in office after a total knee revision for a check up. I'm not sure of what DX code to use since this wasn't a TKA. Any help?
